Battery Smoke Alarm with Precision Detection, Front Battery Access and End-of-Life Alert – First Alert SMI100
A battery smoke alarm provides standalone detection without hardwiring. This white First Alert SMI100 uses Precision Detection sensing designed to meet current industry standards and reduce cooking nuisance alarms while providing warning of smoke in a home.
The included 9V alkaline battery installs through a front-access compartment for easier replacement. A test-silence button supports regular checks, and an end-of-life warning indicates when the alarm itself needs replacement.
